RÉSUMÉ
Objective@#To investigate the correlation between postoperative recurrence and clinical parameters in patients with chronic rhinosinusitis with nasal polyps (CRSwNP), and to study predicitve value of total scores of eosinophils (EOS) and sinus CT for postoperative recurrence.@*Methods@#A retrospective analysis of 264 patients with CRSwNP who were admitted to the First Affiliated Hospital of Wenzhou Medical University from June 2013 to December 2015 was performed. The patient was subjected to a visual analogue scale (VAS) score, a skin prick test, a peripheral blood cell count, a sinus CT score, and a nasal polyp EOS count. All patients underwent endoscopic surgery and were followed up for at least 2 years. The demographic characteristics of the nasal polyps recurrence group and the non-recurrence group were compared with other clinical indicators. Quantitative data were compared by t test or Mann-Whitney U test, qualitative data were compared by chi-square test, and Logistic regression analysis was used for Logistic regression analysis. The risk factors for recurrence were assessed. The best cut-off value was determined by using the receiver operating characteristic (ROC) curve. The predictive value of the parameters was determined by area under curve (AUC). The difference was statistically significant at P<0.05.@*Results@#The recurrence rate of the study patients was 43.56% (115/264). Sex, olfactory VAS score, total sinus CT score, peripheral blood neutrophil ratio, peripheral blood EOS absolute value and proportion, and tissue EOS absolute value and proportion were associated with postoperative recurrence of nasal polyps (χ2=5.241, t=-3.146, t=-7.441, χ2=180.617, t=-5.313, χ2=100.067, t=-7.471, χ2=258.916, all P<0.05), and the tissue EOS ratio and total sinus CT scores have higher predictive value for recurrence of nasal polyps (AUC values were 0.793, 0.767, respectively, all P<0.001). With the EOS ratio of nasal polyps >0.032, the sensitivity of predicting recurrence was 83.48%, the specificity was 56.38%. With the total score of sinus CT>15, the sensitivity of predicting recurrence was 51.30% and the specificity was 87.25%. The combined sensitivity of predictive recurrence was 92.00% and the specificity was 49.20%.@*Conclusion@#The percentage of EOS in nasal polyps and the total score of sinus CT in patients with CRSwNP have better predictive diagnostic value for recurrence of nasal polyps.
